Source Code Scanners is the high performance VCL
library intended for creating analyzers and parsers of
source codes.
It includes components of the C++ lexical analyzer and
the C++ preprocessor, but also contains the full set
of base classes, which provides a possibility to
create lexers and parsers of any other languages.
These components may be used to build applications,
which require the C++ source code analyzing (tools of
helps creating; calculators of expessions; designers
of source codes; interpreters and compilers of C-like
languages and etc.).
The lexical analyzer uses DFAs (Deterministic Finite
Automata) to match tokens found on the character input
stream. DFAs are defined by the set of regular
expressions in a source code and are created at
runtime. More than one automaton (lexical class,
lexical tree) may be defined. Actions attached to
regular expressions (which are executed when that
expression has been matched on the input stream) may
switch from one lexical class to another. The TLexTree
class maintains converting a set of regular
expressions into the DFA array.
Source Code Scanners provides also classes, which
support a work with command-line options, calculating
of constant expressions and etc.
Source Code Scanners is 100% the VCL library that is
written fully in C++.
